Practical Modern Javascript

To get the most out of modern JavaScript, you need learn the latest features of its parent specification, ECMAScript 6 (ES6). This book provides a highly practical look at ES6, without getting lost in the specification or its implementation details. Armed with practical examples, author Nicolas Bevacqua shows you new ways to deal with asynchronous flow control, declare objects or functions, and create proxies or unique sets, among many other features. The first title in Bevacqua’s Modular JavaScript series, Practical Modern JavaScript prepares JavaScript and Node.js developers for applied lessons in modular design, testing, and deployment in subsequent books. This book explains: How JavaScript and its standards development process have evolved Essential ES6 changes, including arrow functions, destructuring, let and const Class syntax for declaring object prototypes, and the new Symbol primitive How to handle flow control with Promises, iterators, generators, and async functions ES6 collection built-in types for creating object maps and unique sets How and when to use the new Proxy and Reflect built-ins Changes to Array, Math, numbers, strings, Unicode, and regular expressions, and other improvements since ES5

Larry demonstrates how to build upon JavaScript’s ease of use, while demystifying its often-cryptic syntax, especially for those who have not programmed before. This book enforces modern JavaScript’s best practices and embraces key Web development approaches such as progressive enhancement and unobtrusive scripting. The author demonstrates loads of real-world code and makes it available for download. You’ll learn about JavaScript itself and the relationship between JavaScript and HTML. Next you’ll explore variables, common operators, and control structures. Then you’ll create functions, handle events, and do more with HTML forms. You’ll master Ajax, work with frameworks, and use JavaScript with PHP to create a complete example. The result is a book that helps you not just tinker with JavaScript but to thoroughly comprehend it. This book includes: Easy step-by-step instruction, ample illustrations, and clear examples Real-world techniques to build your skills Insight into best practices from a veteran Web expert Emphasis on strategies for creating reliable code that will work on all of today’s browsers and devices, even those without JavaScript

If you have a working knowledge of JavaScript and ECMAScript 6 (ES6), this practical guide will help you tackle modular programming to produce code that’s readable, maintainable, and scalable. You’ll learn the fundamentals of modular architecture with JavaScript and the benefits of writing self-contained code at every system level, including the client and server. Nicolás Bevacqua, author of Practical Modern JavaScript, demonstrates how to scale out JavaScript applications by breaking codebases into smaller modules. By following the design practices in this book, senior developers, technical leaders, and software architects will learn how to create modules that are simple and flexible while keeping internal complexity in check. Learn modular design essentials, including how your application will be consumed and what belongs on the interface Design module internals to keep your code readable and its intent clear Reduce complexity by refactoring code and containing and eliminating state Take advantage of modern JavaScript features to write clear programs and reduce complexity Apply Twelve-Factor App principles to frontend and backend JavaScript application development

Exploit the Power of Modern JavaScript and Avoid the Pitfalls JavaScript was originally designed for small-scale programming in web browsers, but modern JavaScript is radically different. Nowadays, JavaScript programmers actively embrace functional, object-oriented, and asynchronous programming, while deprecating error-prone concepts from the past. Modern JavaScript for the Impatient is a complete yet concise guide to JavaScript E6 and beyond. Rather than first requiring you to learn and transition from older versions, it helps you quickly get productive with today’s far more powerful versions and rapidly move from languages such as Java, C#, C, or C++. Bestselling programming author Cay S. Horstmann covers all you need to know, provided in small chunks organized for quick access and easy understanding. Horstmann’s practical insights and sample code help you take advantage of all that’s new, avoid common pitfalls and obsolete features, and make the most of modern JavaScript’s robust toolchains and frameworks. Quickly master modern JavaScript’s implementation of fundamental programming constructs Avoid legacy techniques that create unnecessary complexity and risk Make the most of functional, object-oriented, and asynchronous techniques Use modules to efficiently organize and run complex programs Write more powerful, flexible, and concise programs with metaprogramming Extend JavaScript’s power via JavaScript libraries, frameworks, and platforms Whether you’re just getting started with JavaScript or you’re an experienced developer, this guide will help you write tomorrow’s most robust, efficient, and secure JavaScript code.
